That's right. The only human interaction you're going to get -- talking to your fellow guild members in World of Warcraft online doesn't count -- will be the pimple-faced pizza delivery boy. Pair this service with some form of cell phone-based payment and even that might not be necessary; just tell him to leave it at the door.
You've got to wonder, though, if you've got a case of the midnight munchies and all your speech comes out a little slurred from that, uh, medicinal stuff you've been smoking, how coherent will your text message be? I can just see it now. "I wbnt zaaaaaaaa."
Now, as a self-confessed pizza snob, can someone tell me why someone would want to order a fast food pizza from a chain?
